This has been a happy week for mobile Xbox gamers. Gameloft published the highly anticipated Six-Gunsfor Windows Phone 8, and it’s a free game to boot. But more is always better where games are concerned.

The latest Xbox Red Stripe Deal has you covered then, gamers. Gameloft’s Modern Combat 4 is one sale for $2.99, more than half off the regular price. It’s a killer Windows Phone 8 game that has never been on sale before. Call of Duty and first-person shooter fans won’t want to miss it.

Rounding out the Red Stripe Deals are popular puzzle game Crazy Machines Golden Gears from Viva Media and finance management app myMoneyBook from Tiziano Cacioppolini, both on sale for $1.49. Head past the break for details and Store links.

Modern Combat 4: Zero Hour (Windows Phone 8)

Modern Combat 4 features an exciting single-player campaign as well as a robust multiplayer component. The campaign storyline revolves around a series of terrorist attacks as well as the kidnapping of the US president. Players will take on several different roles throughout the game, including not only heroic military operatives but even the lead enemy (who is a huge jerk)! It’s an excellent campaign.

As you would expect in a game inspired by the Call of Duty series, multiplayer is a major part of the Modern Combat 4 experience. Multiplayer games support up to 12-player matches via local Wi-Fi or online. Don’t expect to fill up a room too often – the matchmaking leaves something to be desired and there’s no way to chat with other players, hence a tiny community. But this sale will provide new players. at least.

Also note that Modern Combat 4 suffers from one broken Achievement. Check out our full review for more details.

myMoneyBook (Windows Phone 7 or 8)

If I have one great weakness (sure, only one!) it’s my money management skills. Totally runs in the family. Every month, my vast Windows Phone Central fortune is squandered away on tequila and señoritas, leaving me broke until the next big payday. That’s why I should get an app like myMoneyBook (all one word, oi) to keep things in order.

Enter your daily receivables/payables in just few steps and set a monthly budget to track your spending.
